CLAIM OF PRIORITY

This application claims the priority under 35 U.S.C. §119(a) to Korean Application Serial No. 10-2015-0163282, which was filed in the Korean Intellectual Property Office on Nov. 20, 2015, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure generally relates to an electronic device, and more particularly to an electronic device that includes a shield structure.

BACKGROUND

An electronic device refers to a device that performs a specific function according to an equipped program, such as an electronic scheduler, a portable multimedia reproducer, a mobile communication terminal, a tablet PC, an image/sound device, a desktop/laptop PC, or a vehicular navigation system, as well as a home appliance. For example, such an electronic device may output information stored therein as sound or an image. Increasingly, as super high speed and large capacity wireless communication have become popular, electronic devices are becoming more multi-functional including providing a function as a mobile communication terminal. For example, a single electronic device that includes a communication function may also include a variety of other functions, such as an entertainment function (e.g., a game function), a multimedia function (e.g., a music/video reproducing function), a communication and security function for mobile banking, a schedule management function, and an e-wallet function.

Such an electronic device may be equipped with electronic components for implementing a communication function, a multimedia function, or the like, and a printed circuit board, on which the electronic components are mounted. While some electronic components are operated, electromagnetic waves may be generated. These electromagnetic waves may affect the operations of other electronic components.

SUMMARY

Electronic components of an electronic device may be mounted on both sides of a printed circuit board. Doing so may facilitate miniaturizing the electronic device. However, there may be a difficulty in provided a space in which the printed circuit board and the electronic components may be disposed. Moreover, as the electronic device incorporates an increasing number of electronic components, electromagnetic wave interference between electronic components, which may degrade the performance of the electronic device, is becoming a greater problem. In order to arrange the printed circuit board and the electronic components within a limited space of the electronic device, two printed circuit boards may be formed in a stacked structure, in which the printed circuit boards face each other. The electronic components may be arranged on the facing faces of the two printed circuit boards such that the electronic devices face each other. Each of the electronic components may be covered by a shield structure.

Various embodiments of the present disclosure may provide an electronic device that is able to be miniaturized and reduced in weight by reducing a space that would otherwise need to be occupied by a shield structure by configuring the electronic components to share the same shield structure.

Various embodiments of the present disclosure may provide an electronic device that is provided with a shield structure, which may be relatively easily installed between the facing faces of two printed circuit boards.

According to various embodiments, an electronic device may include: a housing that includes a first face that faces a first direction, and a second face that faces a second direction, which may be opposite to the first direction; a first printed circuit board that includes a first face that faces the first direction, and a second face that is included within the housing and faces the second direction; a second printed circuit board that is disposed between the second face of the housing and the second face of the first printed circuit board, and includes a first face that faces the first direction and a second face that faces the second direction; at least one first electronic component that is disposed on the second face of the first printed circuit board; at least one second electronic component that is disposed on the first face of the second printed circuit board to be adjacent to the first electronic component; a shield structure that electromagnetically shields the first electronic component and the second electronic component.

The shield structure may include: a metallic plate that is disposed between the first electronic component and the second electronic component; a first side wall that encloses at least a portion of the first electronic component, and may include a first portion that is formed by a portion that extends from the periphery of the metallic plate and is formed by being bent in the first direction; and a second side wall that encloses at least a portion of the second electronic component, and includes a second portion that is formed by another portion that extends from the periphery of the metallic plate and is formed by being bent in the second direction.

According to various embodiments of the present disclosure, the electronic device have the same shield structure for each of the first printed circuit board and the second printed circuit board. Accordingly, it is possible to reduce the height between the first printed circuit board and the second printed circuit board since separate shield structures for each of the first and second printed circuit boards are not necessary.

In addition, according to various embodiments of the present disclosure, the electronic device may be configured to reduce the connecting members that interconnect the printed circuit boards and the shield members. Accordingly, it is possible to reduce the time and cost that are required for installing the shield structures.

These and other features of the present disclosure are more fully described hereinbelow.
